Although I might add that I believe (possibly incorrectly) that melee hits occur every 8 pulses. This can be verified by attempting to spam a one pulse lag move like nod during combat. I think you get in 8 nods between rounds, the last one landing right before the next.

Also, this bit of game mechanic information is both very obvious and also very important if you wish to understand how movement lag and other non combat oriented lag functions.
